Process.Start() 找不到文件？

Question

我正在做一个助手，我想让它打开应用程序。它只打开某些应用程序，即 chrome.exe(Chrome) 和 devenv.exe(Visual Studio).

我还有 4 个应用程序，它们是 Spotify.exe(Spotify)、Discord.exe(Discord)、obs64.exe(OBS Studio) 和 Steam.exe(Steam)。当我告诉助手打开某个应用程序时，我收到一条错误消息：

"System.ComponentModel.Win32Exception: 'The system cannot find the file specified'".

所有这些应用程序的错误都是一样的。这是我的代码：

        SpeechSynthesizer ZeroTwo;
        SpeechRecognitionEngine ZeroTwoEars;
        SoundPlayer ZeroTwoGreeting;
        Grammar ZeroTwoGrammar;

        bool ZeroTwoSearch = false;

        public Form1()
        {
            InitializeComponent();

            // Sound player

            ZeroTwoGreeting = new SoundPlayer(@"c:/Users/User/Desktop/Zero Two Sound Files/dahling ohaio.wav");

            // Speech Synthesizer

            ZeroTwo = new SpeechSynthesizer();      

            // Speech Recognition

            ZeroTwoEars = new SpeechRecognitionEngine();
            Choices list = new Choices();

            list.Add(new string[] { 

                // Greetings

                "Ohaio, zero two",

                // Google search

                "Zero two, search for",

                // Open apps

                "Zero two, open discord",

                "Zero two, open steam",
                "Zero two, open obs"
            } );

            ZeroTwoGrammar = new Grammar(new GrammarBuilder(list));

            try

                ZeroTwoEars.RequestRecognizerUpdate();

                ZeroTwoEars.LoadGrammar(ZeroTwoGrammar);

                ZeroTwoEars.SpeechRecognized += ZeroTwoEars_SpeechRecognized;

                ZeroTwoEars.SetInputToDefaultAudioDevice();

                ZeroTwoEars.RecognizeAsync(RecognizeMode.Multiple);

            }
            catch { }

Chrome.exe 和 Devenv.exe 自动运行的原因是，对于这两个应用程序，它们的路径（它们所在的文件夹）是在系统 Path 环境中声明的多变的。有 2 个解决方案。

您必须通过设置 的完整路径来调用您的 Discoord.exe 应用程序，例如：

Process.Start("C:\\Users\\AppData\\Local\\Discord\\app-0.0.307\\Discord.exe");
在您的电脑系统中设置环境路径。 例如。看下面的 screen-shot:
